Method and device for biological tissue regeneration (embodiments)

Abstract

The proposed method is for the regeneration of biological tissues with restoration of functional properties, characteristics and structure thereof, in which tissues are subjected to a predetermined degree of mechanically-induced trauma through the creation, in the desired areas, of at least one region of interference between acoustic waves generated by at least two sources and propagating in the tissues to be regenerated, with the possibility of subsequent natural regeneration of the corresponding biological tissues in said areas. Also proposed are various embodiments of the above method. To achieve the rejuvenation effect of different biological tissues located at different depths, the microtrauma areas are created with no thermal effect, i.e. neither evaporation nor coagulation of all overlying tissues, i.e. regeneration of the tissues occurs with no fibrous cell growth, suggesting that not only visual but also actual rejuvenation took place.

What is claimed: 
     
         1 . A method for rejuvenation of biological tissue and restoration of functional properties, characteristics, and structure thereof by creating microtrauma sites in desired areas of biological tissue, followed by natural regeneration of corresponding biological tissue in specified areas, wherein said tissue are subjected to specified mechanically-induced trauma by affecting the desired areas with at least one site of interference of acoustic waves of an explosive nature generated by at least two sources and propagating through the tissue to be regenerated. 
     
     
         2 . The method according to  claim 1 , wherein all epicenters of the acoustic waves are located at equal distances from one another, selected from a 10 μm to 1 cm range. 
     
     
         3 . The method according to  claim 2 , wherein the level of mechanically-induced trauma is selected from the range between a level providing destruction of cell membrane integrity only and a level providing full destruction of cells in the tissue to be rejuvenated. 
     
     
         4 . The method according to  claim 3 , comprising using a laser light source and a system for converting spatial distribution of beam intensity to form on the surface to be rejuvenated or the overlaying biological tissue a periodic structure with maxima and minima of light energy, forming, due to the effective absorption of energy in said maxima, a plurality of acoustic wave epicenters.
